it does not leave red and yellow light and move to green light anymore... Rather it goes back to red light after blinking red and light.
the electricity is alright as Usual, this I'm sure of.
What could be the cause?

It only does this occasionally when light current is very low, irregular or poor in one way or the other... But the light current is okay this time.

It started this just this midnight.
Pls what could be the cause(s)?

Omoh...me and you dey experience the same issue ooooo

There should be a small switch on it. Check whether it's set to delay

Post a picture of the device. Let me be sure it’s more expensive than the two thousand Naira ones I buy regularly. This one you opened three threads based on the matter, it’s like you don’t come across such sum normally.
